wow Lua进行http调用

local socket = require("socket")

local host = "www.example.com"
local path = "/"
local response = ""

local conn = socket.connect(host, 80)
conn:send("GET " .. path .. " HTTP/1.1\r\n")
conn:send("Host: " .. host .. "\r\n")
conn:send("Connection: close\r\n\r\n")

while true do
    local chunk, status, partial = conn:receive(1024)
    response = response .. chunk or partial

    if status == "closed" then
        break
    end
end

print(response)

conn:close()
